Improvement in lubricating compounds

RIGHT TO LYMAN D. JOHNSON, OF ALBANY, NEW YORK.

IMPROVEMENT IN LUBRICATING COMPOUNDS.

Specification forming part of Letters Patent No. 175,986, dated April11, 1876 application filed August 2, 1875 To all whom it may concern:

'Be it known that 1, Solomon B. HORTON, of Pownal, in the State ofVermont, have invented a new and Improved Lubricating Compound; and I dohereby declare that the following is a description thereof:

This invention relates to a liquid or fluid compound for lubricatingcutting-tools employed to operate with metal, and also journals orshaftings in their bearings, and consists in a composition formed bymixing lard or lard-oil, Water, and sal soda.

To prepare this lubricating compound take eight (8) gallons of softWater, heat'the same, and while hot stir in one (l) quart of lard orlard-oil and two (2) pounds of sal-soda. Oontinue the stirring of thebody until the several ingredients become thoroughly incorporated and auniform consistency of body is produced. The liquid thus produced isthen to be allowed to cool and settle preferably, although it. may beimmediately used.

Made with the above-named ingredients, in the proportions above given,this compound may be repeatedly used for lubricating cutting-toolsemployed to work iron in lathes, planers, screw-cutting machines, orother metal-cutting tools used with machinery, in lieu of oil.

This lnbricator may be produced at the cost of a few cents per gallon,and has the advantage of lasting longer than oil before being used up;is more cleanly, and enables the tool to operate for a longer time withits edge preserved in good order than when used with any of the ordinarylubricating oils heretofore employed with cutting-tools. In its use withjournals and bearings this compound has the advantage of being clean andfree from gumming, and permits the journals to be run at high speed orunder immense pressure without becoming heated to any considerabletemperature as may be had with animal, vegetable, or mineral oilsheretofore employed, while all liability of being fired is whollyremoved.

For heavy work, such as in turning chilled iron, steel, or wrought-ironwith a heavy chip, the amount of water above stated may be reduced fromten to twenty per cent, while for light work the quantity of water maybe increased about the same per cent, without materially affecting thenature of this compound for lubricating.

It should be understood that hard water should in no case be employed,as it will cause a partial precipitation of the soda and lard, and willprevent a uniform consistency of the body of the compound; and thatsperm or whale oils should in no case be employed, as they will notbecome fully incorporated in the body but will eventually rise to thetop in part.

This compound is to be applied or used the same as any of the oilsheretofore employed for like purposes.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

The metalcuttin g-tool lubricatingcompound above described, composed ofwater, lard or lard-oil, and sal soda, in the proportions above setforth, for the purpose specified.

SOLOMON B. HORTON.
